4' Claims.

Another object of the invention is to provide a strip stamp or the likewhich is provided with a slow-setting adhesive at the portion thereofwhich abuts said metal cap, and to provide said strip stamp or the likwith ordinary quick-setting adhesive at the portions which contact withthe glass wall of the neck of the bottle.

Other objects of my invention will be set forth in the followingdescription and drawing which illustrates a preferred embodiment. of theinvention, it being understood that the above statement of the objectsof my invention is intended to generally explain the same withoutlimiting it in any manner.

Fig. 1 is a perspective view showing a part of a bottle which is sealedby means of a lacquered metal cap, and to which th improved strip stamphas been applied.

Fig. 2 is a plan view of the improved strip stamp, showing the face ofthe stamp to which the adhesive has been applied.

Fig. 3 is a diagrammatic front elevation of Fig. 2.

In bottling whiskey and numerous other beverages, it is necessary toapply a strip stamp over the metal cap which is used for sealing theneck of the bottle. These caps have lacquer on their exterior walls andit has been impossible to devise a quick-setting adhesive which willpenetrate said lacquer and which will dry rapidly.

Under present commercial practice, it has been customary to coat oneside of the strip stamp throughout with the same adhesive, in order toconnect the stamp to the top and to the depending skirt of thelacquer-coated cap, and also to connect the stamp to the glass wall ofthe neck of the bottle below the skirt of the cap. This adhesive wasnecessarily a slow-setting adhesive, whose composition enabled it topenetrate the lacquer of the metal cap, so as to provide the necessaryadhesion to the top of the cap. The ordinary quick-setting adhesive,which is effective to connect the strip stamp to the glass wall of theneck, dried or set too rapidly to connect the stamp to the lacquercoating of the cap.

Since this adhesive was a slow-setting adhesive it was necessary toapply the strip stamp to the neck of the bottle at a first station of amachine by means of wipers, and then to feed the bottle on the belt ofthis machine for one to two minutes, or even more, and then to appl thewipers of the machine again to the strip stamp at a second station ofthe machine, in order to complete the connection between the strip stampand the cap and the glass wall of the bottle. This delay, and thenecessity of using a long belt, and the use of Wipers at two stations,is eliminated by my invention.

Fig. 1 shows the bottle I, having the neck 2, which is sealed with theordinary lacquered metal cap 3. This metal cap 3 is of conventionalconstruction so that it is shown only diagrammatically. Ordinarily, thelacquer coating is applied only to the top wall of the cap 3, but it mayalso be applied to its skirt. The interior of the cap 3 is usuallyprovided with a gasket made of cork or the like.

As shown in Fig. 2, the central portion of the strip stamp 4, betweenthe lines 5 and 6, is coated with the usual slow-setting adhesive whichcan penetrate the lacquer coating of the cap 3, so as to provide theproper adhesion. The central area A of the strip stamp 4 is ofsufficient length to abut the top wall of the cap 3, and also to abutthe depending skirt of the cap 3. Therefore the entire area of the stripstamp t which contacts with the lacquer coating of the cap 3, isprovided with said slow-setting adhesive.

The end areas B and C are provided with the usual quick-settingadhesive, which can adhere readily to the glass Wall of the neck of thebottle.

The strip stamp is applied by the wipers of the usual machine in theordinary manner, so that no change in manipulation and no change in thewell-known machine is required. Since the adhesive on the areas B and Csets very quickly, the strip stamp is firmly maintained in position bysaid quick-setting adhesive, and the slow-setting adhesive in the area Ais maintained with suitable pressure against the lacquered wall of thecap 3, by the quick-setting adhesive in areas B and C. Therefore, thebottle can be taken off the machine after a single operation of thewipers. After the bottle has been taken off the machine, theslow-setting adhesive sets and it produces perfect adhesion with thelacquered cap, because the quick-setting adhesive maintains theslow-setting adhesive abutting the lacquer coating, under suitablepressure.

While the invention is of particular value in connection with bottleswhich contain whiskey and which must be provided with strip stamps underthe law, the invention is not necessarily limited thereto. The containermay be of any type and its wall may be made of any material to which apaper strip can be connected by a quick-setting adhesive.

When adhesive is applied to paper, in order to attach the paper toanother article, the adhesive passes through two definite steps from thetime that the adhesive is applied, until the adhesive has thoroughlyset. The adhesive must first form the initial tacky connection. In suchcondition the paper strip is connected to the other article to theextent that the paper strip will not separate from the article by thecurling of said paper strip. However, in such initial condition thepaper strip can be separated from the cap or bottle or the like, withouttearing the paper. In the second condition of the adhesive, saidadhesive has set suificiently so that the paper cannot be separated fromthe bottle or cap or the like, without tearing the paper. In the secondcondition, there may be some moisture in the adhesive and the adhesivemay not be thoroughly dry.

According to my invention, the initial tacky condition is the importantelement, because the period of time which is required to dry theadhesive thoroughly is not important. The important factor is to fix thestrip stamp properly in position, so that it will not separate bycurling or the like.

As an example of the quick-setting adhesive, I refer to the well-knowntype which is made from sago starch. This could be diluted with water.Upon applying the strip stamp which has been coated with this adhesiveto glass, the initial tacky condition is secured immediately. The timefor setting said quick-setting adhesive is from seconds to seconds.

As an example of the slow-setting adhesive, I refer to the lacquer typeof adhesive which must be diluted with a special solvent thinner. Theinitial tacky condition is secured in a period of 50 seconds to 70seconds, and the time of setting to the second condition is from 4minutes to 6 minutes.

The above periods of time are estimated upon the use of a very thincoating of adhesive. If a thicker coating of adhesive is required, alonger period of time is required for evaporating the liquid ingredientor ingredients of the adhesive. The quick-setting adhesive is designatedcommercially as No. Special, and the slow-setting adhesive is designatedcommercially as D3-A.

The above example is merely given by way of illustration and theinvention is not limited thereto.

Generally speaking, a quick-setting adhesive is one which will have aninitial tack immediately upon application, and a slow-setting adhesiveis one which requires from seconds to 70 seconds before the initialtacky condition is secured,

Whenever I refer to a strip stamp in the claims, I include all similardevices made of paper and other materials, which adhere to the seal of acontainer, and also to the wall of the container below the seal, inorder to detect the removal of the seal or sealing device. The wall ofthe container may be made of glass, porcelain, of various syntheticresins, of various plastics, such as cellulose acetate, etc. Theseequivalent materials are included in the claims when I refer to glass.The wipers of the machine downwardly pull the depending portions of thestrip stamp by a downward movement, while pressing said dependingportions against the glass wall of the bottle. The quick-settingadhesive has sufficient adhesion to the glass wall, prior to the settingof said quick-setting adhesive, to maintain the top portion of the stripstamp pressed against the top of the cap. When I refer to a strip stampin a claim or claims, I include similar devices which will indicate whena closure device has been ruptured or removed.

I have described a preferred embodiment of my invention, but it is clearthat numerous changes and omissions can be made without departing fromits spirit.

I claim:

1. A strip stamp having layers of quick-setting adhesive at itsend-portions and a layer of slow-setting adhesive intermediate saidlayers of quick-setting adhesive, all said layers being on the same faceof said strip stamp, said slowsetting adhesive being adherent to alacquered metal surface so that it can connect the respective part ofthe strip stamp to the lacquered surface of a metal member, saidquick-setting adhesive forming an initial tacky connection with glasssubstantially immediately, so that when the end-portions of the stampare applied to glass, said end-portions are then held to said glasssubstantially immediately solely by said initial tacky connection, andsaid end-portions will not curl away from the glass.

2. A strip stamp having a layer of slow-setting adhesive on its centralportion, and layers of quick-setting adhesive at its end portions, saidslow-setting adhesive being adapted to connect said central portion to alacquered metal sealing member, said quick-setting adhesive beingadapted to connect said end-portions to non-metallic material.

3. A strip stamp having a layer of slow-setting adhesive on its centralportion, and layers of quick-setting adhesive at its end portions, saidslow-setting adhesive being adapted to connect said central portion to alacquered metal sealing member, said quick-setting adhesive beingadapted to connect said end-portions to nonmetallic material, saidslow-setting adhesive having an initial tack in 50-70 seconds, saidquick-setting adhesive having an immediate initial tack.

4. In combination, a container having a glass wall and a sealing memberwhich is made of lacquered metal, a strip stamp having its top portionconnected to said lacquered sealing member by a slow-setting adhesive,the end portions of said strip stamp being connected by a quick-settingadhesive to said glass wall below said sealing member.
